In this course you will learn how to design the type of training that takes advantage of the plastic nature of the athlete’s body so you mold the right phenotype for a sport. We explore ways the muscular system can be designed to generate higher force and power and the type of training needed to mold the athlete's physical capacity so it meets the energy and biochemical demands of the sport.
We also examine the cost of plasticity when it is carried beyond the ability of the body to adjust itself to meet the imposed training stresses. The cost of overextending plasticity comes in the form injuries and chronic fatigue. In essence, a coach can push the athlete’s body too far and it can fail. Upon completion of this course you will be able to assemble a scientifically sound annual training plan.

its very very understandable and i really gain a lot from it please keep the work.thanks

From the lesson

Chronic Fatigue Due to Overtraining

When an athlete is underperforming, and you don’t know why, suspect chronic fatigue due to overtraining as the prime contributing factor. Unfortunately, because we don’t fully understand chronic fatigue our knowledge about overtraining remains scant. Hans Selye’s General Adaptation framework suggests it is likely due to too much training and insufficient recovery that leads to a prolonged maladaptation of physiological systems and structures. In this module you are provided insight into chronic fatigue and its relationship to overtraining.

Transcript

So we've talked about sympathetic overtraining. Now we'll discuss parasympathetic overtraining. When the activity of the sympathetic nervous system is fatigued, and the body remains under stress, the nucleus ambiguus vagal brake is unable to apply its effect. Remember, the vagal brake will only apply if the body is in homeostasis. So the body is left with one final defensive strategy, and that's the dorsal motor nucleus, or DMNX. Everything is slowed down with the DMNX, including the heart rate. The name parasympathetic overtraining is used to reflect the abnormal, low resting heart rate and the delayed heart rate recovery after a training session. However, this is not caused by the nucleus ambiguus. Rather, it suggests that the heart is now being controlled by the ancient dorsal motor nucleus, or DMNX. When the nucleus ambiguus is applying the break there is a high heart rate variability. And when the dorsal motor nucleus, or DMNX, is applying its effect on the heart, there is hardly any heart rate variability. A low heart rate variability is very noticeable in long-term, chronically fatigued, overtrained athletes. And lack of heart rate variability is accompanied by no desire to compete and train. It's accompanied by depression, chronic injuries, exhaustion and a marked diminished performance. Low heart rate that is below the athlete's normal resting heart rate is clinically referred to as bradycardia. And it's a very bad symptom because it suggests that the heart is being controlled by the DMNX, and not the nucleus ambiguous. The ancient DMNX provides way too much vagal tone. Now the athletes who are in the third phase of parasympathetic overtraining are serious ill, so take it seriously. Recovery and return to their previous optimal levels of performance is a really difficult task. Parasympathetic overtraining is often referred to as Addison's disease, or Addison's overtraining, because the symptoms are very similar to those exhibited by people who have Addison's disease. And President Kennedy had Addison's disease. Addison's disease occurs when the adrenal glands do not produce enough cortisol. And in the case of a severely overtrained athlete, long-term overtraining, reduced cortisol is possibly due to adrenal insufficiency. The DMNX explains many of the symptoms described by Alberto Salazar. Recovery and return to previous high levels of performance is a very difficult task, and serious long-term health problems can occur. The lesson here is don't go there with the athlete's training, avoid it at all cost.
